The preclinical safety assessment of novel nanotechnology-based drug products frequently relies on in vitro assays, especially during the early stages of product development, due to the limited quantities of nanomaterials available for such studies. The majority of immunological tests require donor blood. To enable such tests one has to prevent the blood from coagulating, which is usually achie...
BACKGROUND Inflammatory cytokines in bone marrow may impair hematolymphopoiesis in human immunodeficiency virus (HIV)-infected subjects who do not experience reconstitution of CD4(+) T cells despite suppression of virus replication while receiving highly active antiretroviral therapy (HAART) (immunological nonresponders). METHODS Bone marrow samples from 12 immunological nonresponders receivi...
A biophysical and immunological method for characterization of ribonucleic acid type C virus suspensions is described. The method provides a relationship to the total viral mass concentration of the particle titer, the gs antigen titer, and the ultraviolet absorbance (268 nm) of 2% sodium dodecyl sulfate digests. Data for murine, rat, feline, and hamster viruses are shown to be analogous within...
AIM To evaluate whether the combination of the peripheral blood CD4+ adenosine triphosphate activity (ATP) assay (ImmuKnow assay: IMK assay) and cytochrome P450 3A5 (CYP3A5) genotype assay is useful for monitoring of immunological aspects in the patient followup of more than one year after living donor liver transplantation (LDLT). METHODS Forty-nine patients, who underwent LDLT more than one...

The detection of immunological phenomena in pernicious anaemia (Schwartz, 1958; Taylor, 1959) introduced the concept of immunological assay of intrinsic factor. Several methods in which antibodies against intrinsic factor are used are now available (Jeffries and Sleisenger, 1965; Herbert, Gottlieb, Lau, and Wasserman, 1964; Abels, Bouma, Jansz, Woldring, Bakker, and Nieweg, 1963; Ardeman Chanar...
BACKGROUND Hepcidin is a 25-aminoacid cysteine-rich iron regulating peptide. Increased hepcidin concentrations lead to iron sequestration in macrophages, contributing to the pathogenesis of anaemia of chronic disease whereas decreased hepcidin is observed in iron deficiency and primary iron overload diseases such as hereditary hemochromatosis. Hepcidin quantification in human blood or urine may...
Trichomoniasis is a common sexually transmitted disease with an estimated incidence of 4 million to 8 million cases a year in the United States. The most commonly used method of diagnosis is a direct microscopic observation (wet mount) of vaginal secretions and, although both rapid and inexpensive, the sensitivity of this technique is generally 50 to 70%. We developed an indirect enzyme-linked ...
